2.3 Connectors

2.3.1 Power Cable

The ATX power supply uses 20-pin connector shown below. Make sure you
plug in the right direction.
Caution: Make sure that the power supply is off
before connecting or disconnecting the power cable.

2.3.2 Fan

Plug in the fan cable to the fan connectors onboard. The fan connectors are
marked CPUFAN1, CPUFAN2 and FAN on the system board. You can plug
the CPU fan cable to both the 3-pin fan connector CPUFAN1 and the 2-pin fan
connector CPUFAN2. FAN can be reserved for the housing fan. Note that only
CPUFAN1 and FAN support the fan monitoring function, because a 3-pin fan
has an extra pin called SENSE, which periodically sends fan signal out.
